Title: Metal collector
Inventor: HOSODA KAZUO
IPC: B09B3/00
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a metal collector improved in resistance to decomposition by microorganisms without detriment to the metal-collecting capability. SOLUTION: This metal collector is a reaction product of a polyamine and a diepoxy compound, at least either of these reactants having an aromatic ring, and has a structure containing a metal-collecting functional group bonded to a nitrogen atom derived from the polyamine. When flocks generated in wastewater treatment using the collector or solid wastes treated with the collector are treated by burying in soil or the like, the collector is not decomposed by microorganisms and hence does not cause a metal to be eluted, preventing recontamination, etc. Though having an aromatic ring in the molecular structure, the collector is more hydrophilic than a conventional metal collector having an aromatic ring and exhibits an improved resistance to decomposition by microorganisms without detriment to the metal-collecting capability.

Inventor: MIZUTA TAKAYUKI
IPC: H01L21/336
Filed: 1986-11-17
Abstract: PURPOSE:To obtain fine working and desired characteristics easily by forming a gate at the center of a recessed section through self-alignment. CONSTITUTION:A field oxide film in a field-effect transistor forming region 4 in a field oxide film shaped onto a substrate 1 is removed selectively, a gate oxide film 2a and polycrystalline silicon are deposited to a predetermined thickness, and a resist 6 is formed selectively only in a polycrystalline silicon recess 10 on a gate forming region. Polycrystalline silicon is etched in an anisotropic manner to shape a gate electrode. An unnecessary section except the gate electrode and the gate oxide film is got rid of, and source-drain regions are formed while an inter-layer insulating film is shaped and an electrode wiring is conducted. Accordingly, gate electrode length can be formed in size shorter than the size of a mask, and the gate electrode can be arranged at the center of the recess through self-alignment, thus easily obtaining fine working and desired characteristics.

Title: Power factor detector
Inventor: TANAKA TOMIO
IPC: G01R21/00
Filed: 1989-10-23
Abstract: PURPOSE:To enable operation of detecting power factors with a high reliability by shifting a phase difference at which a current input is inverted using a phase delay circuit to prevent malfunctioning near the inversion of phase with a control of a power factor detector. CONSTITUTION:A power factor is detected with a power factor detector 4 by an output of a generator 1. Here, as a phase delay circuit 10 is added to the preceding stage of a second zero cross switch 7 as current I1, an input of the second zero cross switch 7 delays by a fixed alpha degree in phase (this a degree can be set arbitrarily). Hence, detection characteristic of a power factor is shifted by alpha degree. In other words, as a phase difference at which an output of the power factor detector 4 is inverted can be shifted, with an advancing of an actual power factor, a phase in which inversion occurs as well when the power factor is zero can be used for the control of the power factor detector far away from a application range.

Filed: 1984-12-28
Abstract: PURPOSE:To obtain a parity generating circuit and a parity detection circuit with simple circuit constitution by combining a T flip-flop with a data converting means and using Q and Q' outputs so as to generate and detect a parity. CONSTITUTION:When a serial data inputted to a terminal T is 01011010, since the Q output of the T flip-flop 1 is changed as 0 1, 1 0 synchronously with a clock only when the T input is logical 1, the Q output in this case is changed as 0 1 0 1 0, while the Q' is changed as 1 0 1 0 1. In other words, when the input of a serial data is finished, the Q output goes to logical 0 and the Q' output goes to logical 1. In using a selection circuit 3 to select the Q output, an even number parity bit is obtained, and in selecting the Q' output, an odd number parity is obtained. Thus, it is not required to combine lots of logical circuits complicatedly and the parity generation and detection circuit is obtained with very simple constitution.
